GRE Geometry - Figure to Scale

First, it's important to note that, unless you are told otherwise, figures are NOT drawn to scale, so just because one angle looks as if it were equal in measure to another angle, then you can't assume that the angles are equal (or close). However, often-times
you will be told explicitly Figure is drawn to scale, meaning that if an angle looks as if it is bigger than another angle, then it is so.
